MAX680ESA Equivalent & Substitute Parts

Part Overview

The MAX680ESA is a charge pump switching regulator IC that generates positive and negative dual rail outputs from a single input supply. This component functions as a ratiometric regulator producing fixed ±2Vin outputs with 10mA per rail capacity. The MAX680ESA is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. Active substitute parts maintain identical electrical specifications and package configurations while offering current manufacturing availability and ongoing supplier support.

Substitute Part Grouping Explanation

Substitution of the MAX680ESA is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain:

• Identical input voltage range (2V to 6V)
• Identical output configuration (positive and negative dual rail)
• Identical fixed output voltage ratio (±2Vin)
• Identical output current capacity (10mA per rail)
• Identical switching frequency (8kHz)
• Identical operating temperature range (-40°C to 85°C)
• Identical package type and dimensions (8-SOIC, 0.154", 3.90mm Width)
• Identical surface mount mounting type
• Compliance with ROHS3 and MSL 1 specifications

The MAX680ESA+ meets all substitution criteria as a direct equivalent part. The primary distinction is product status: MAX680ESA is obsolete while MAX680ESA+ is active, and packaging format differs (MAX680ESA+ supplied in Tube packaging versus standard packaging for MAX680ESA).

Parameter Comparison

Engineering Selection Recommendations

The MAX680ESA+ is the direct active equivalent for the obsolete MAX680ESA. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package configurations. Selection of MAX680ESA+ is appropriate for new designs and production applications requiring dual rail charge pump regulation within the specified input and output voltage ranges.

Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity classification, satisfying regulatory and environmental requirements. The transition from MAX680ESA to MAX680ESA+ involves no functional or electrical trade-offs, as all critical parameters remain unchanged. Packaging format (Tube for MAX680ESA+) represents a standard supply variation without impact on component performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can MAX680ESA+ directly replace MAX680ESA in existing designs?

A: Yes. MAX680ESA+ is electrically and mechanically identical to MAX680ESA. All electrical parameters, output specifications, operating ranges, and package dimensions are equivalent. Direct substitution requires no circuit modifications or design changes.

Q: What is the primary reason for substituting MAX680ESA?

A: MAX680ESA is classified as obsolete. MAX680ESA+ is the active equivalent part, ensuring continued manufacturing availability and supplier support for new production and design implementations.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both MAX680ESA and MAX680ESA+ maintain identical ROHS3 compliance status and MSL 1 moisture sensitivity classification. Regulatory and environmental certifications are equivalent.

Q: Does the 8-SOIC package remain the same for both parts?

A: Yes. Both parts use the 8-SOIC package with identical dimensions (0.154", 3.90mm Width). PCB footprints and land patterns are identical, requiring no layout modifications.

Q: What is the significance of the "+" designation in MAX680ESA+?

A: The "+" designation indicates the active production variant. This notation distinguishes the current manufacturing part from the obsolete predecessor while maintaining full electrical and mechanical equivalence.

Q: Are input and output voltage specifications identical?

A: Yes. Both parts accept 2V to 6V input and produce fixed ±2Vin dual rail outputs at 10mA per rail. Switching frequency (8kHz) and operating temperature range (-40°C to 85°C) are identical.
